Description

Vibration separation screen

Technical field

The utility model belongs to feed processing technology more particularly to a kind of vibration separation screen.

Background technique

In feed preparation, carrying out sieving processing to feed is to guarantee the important step of feed production quality, sieving Processing can remove the impurity in feed and filter out the coarse fodder in feed, effectively filter out and do not meet selected feed particle diameter Impurity improves feeding quality so that the feed granules that production obtains are uniform.

Patent CN207655487U discloses a kind of feed multistage filtering sieve, which includes first sieve and fine screen net, First sieve is set to the top of fine screen net, the multiple filtration to feed is realized, thus finer to feed granules size It is screened.

However, in feed filter process, as easily making there are feed granules similar in some partial sizes and screen mesh At the blocking of sieve, screening efficiency is influenced.In order to restore the screening efficiency of sieve, need periodically manually to carry out sieve wire side clear Reason, increases labour cost, more thoroughly clear in order to carry out to each sieve especially during feed multistage filtering Reason, it is sometimes desirable to each sieve be disassembled and cleared up respectively, operation difficulty is increased, reduce screening efficiency.

Utility model content

Place in view of the shortcomings of the prior art, the utility model proposes a kind of vibration separation screens, can be realized to feeding The multi-stage screening of material, while avoiding feed granules blocking sieve.

In order to achieve the above object, the technical solution adopted in the utility model are as follows:

Vibration separation screen, the vibrating motor including sieve nest and for driving the sieve nest vibration, the sieve nest includes from upper Successively the first sieve disposed in parallel, the second sieve, third sieve and the 4th sieve under, and for fixing first sieve Net, the second sieve, third sieve and the 4th sieve bracket；Between first sieve and the second sieve and the third Between sieve and the 4th sieve, it is placed with bouncing ball respectively；The sieve diameter of first sieve is greater than the third sieve Sieve diameter, the sieve diameter of second sieve and the 4th sieve is less than the diameter of the bouncing ball and is greater than described first The sieve diameter of sieve and third sieve.

Preferably, between first sieve and the second sieve and between the third sieve and the 4th sieve, It is respectively arranged with grid, the grid is by space, third sieve and the 4th sieve between first sieve and the second sieve Between space be divided into multiple sieve lattice, the bouncing ball is distributed in each sieve lattice.

Preferably, the sieve nest is exported equipped with finished product feedstuff, finished product feedstuff outlet and second sieve and the Space between three sieves is connected.

Preferably, the lower section of the 4th sieve is equipped with waste material bucket, the waste material bucket bottom angled and its lowermost end is set There is waste outlet.

Compared with prior art, the utility model has the beneficial effects that:

1, vibration separation screen provided by the utility model includes multiple sieves, realizes the multi-stage screening to feed, obtains Finished product feedstuff uniform particle sizes, condition is good.

2, it is placed with bouncing ball in the sieve nest of vibration separation screen provided by the utility model, sieve is patted by bouncing ball up and down Net wire side reduces the clogging of sieve wire side.

Specific embodiment

In the following, the utility model is specifically described by illustrative embodiment.It should be appreciated, however, that not having In the case where being further discussed below, element, structure and features in an embodiment can also be advantageously incorporated into other realities It applies in mode.

In the description of the present invention, it should be noted that term "inner", "outside", "upper", "lower", etc. instructions side Position or positional relationship be based on attached positional relationship shown in FIG. 1, be merely for convenience of describing the present invention and simplifying the description, and It is not that the device of indication or suggestion meaning or element must have a particular orientation, be constructed and operated in a specific orientation, therefore It should not be understood as limiting the present invention.In addition, term " first ", " second ", " third ", " the 4th " are only used for description mesh , it is not understood to indicate or imply relative importance.

As shown in Figure 1, the utility model relates to a kind of multistage sieves of vibration, the vibration including sieve nest and for driving sieve nest to vibrate Dynamic motor 12, sieve nest include that successively the first sieve 1 disposed in parallel, the second sieve 2, third sieve 3 and the 4th sieve from top to bottom Net 4, and the bracket 5 for fixing the first sieve 1, the second sieve 2, third sieve 3 and the 4th sieve 4；First sieve 1 and Between two sieves 2 and between third sieve 3 and the 4th sieve 4, it is placed with bouncing ball 8 respectively；The sieve pore of first sieve 1 Diameter is greater than the sieve diameter of third sieve 3, the sieve diameter of the second sieve 2 and the 4th sieve 4 be less than the diameter of bouncing ball 8 and Greater than the sieve diameter of the first sieve 1 and third sieve 3.

In above-mentioned vibration multistage sieve, the position of vibrating motor 12 can be adjusted according to actual needs；In sieve nest First sieve 1 and third sieve 3 mainly play a part of to sieve feed, and the second sieve 2 and the 4th sieve 4 mainly play support bouncing ball Effect, sieving actoion is had no to feed.When sieving feed, the biggish feed of partial size is intercepted on the first sieve 1, other Then feed is sieved by third sieve 3 by the second sieve 2, the feed for meeting finished product feedstuff Particle size requirements is trapped within the In space between two sieves 2 and third sieve 3, the lesser feed impurity of partial size after third sieve 3 and the 4th sieve 4 by flowing Out.While feed screening, wire side is patted by about 8 bouncing ball of setting, it is possible to reduce the clogging of sieve wire side. It should be noted that the first sieve 1 and third sieve 3 can be substituted for according to the Particle size requirements of different feeds with different sieve pores The sieve of size, to meet the processing requirement of different feeds.

In order to guarantee that the surface of sieve is uniformly patted, improves and pat efficiency, as depicted in figs. 1 and 2, the first sieve 1 and second between sieve 2 and between third sieve 3 and the 4th sieve 4, is respectively arranged with grid 6, and grid 6 is by the first sieve Space, third sieve 3 between net 1 and the second sieve 2 and the space between the 4th sieve 4 are divided into multiple sieve lattice 7, bouncing ball 8 are distributed in each sieve lattice 7.It should be noted that difference can be placed in each sieve lattice 7 according to actual process demand The bouncing ball 8 of quantity.

In addition it is also necessary to explanation, as shown in Figure 1, sieve nest is equipped with finished product feedstuff outlet 9, finished product feedstuff outlet 9 and the Space between two sieves 2 and third sieve 3 is connected, for exporting the finished product feeding for meeting feed particle diameter requirement after screening Material.

In order to facilitate the output of the lesser feed impurity of partial size, the lower section of the 4th sieve 4 is equipped with waste material bucket 11, waste material bucket 11 Bottom angled and its lowermost end are equipped with waste outlet 10.

The working method of above-mentioned vibration separation screen is as follows:

Vibrating motor 12 is opened, sieve nest vibrates under the driving of vibrating motor；Feed to be screened is put into above sieve nest, Feed falls under the effect of gravity, by the screening of the first sieve 1 and third sieve 3, meets the feeding of finished product feedstuff Particle size requirements Material is exported from 9 output of finished product feedstuff outlet, the lesser feed impurity of partial size from waste outlet 10.While feed screening, respectively The bouncing ball 8 sieved in lattice 7 ceaselessly pats sieve wire side up and down, is on the one hand conducive to the lesser impurity of partial size in feed granules and fills Divide and filter out, on the other hand can prevent the blocking sieve of feed granules similar in partial size and screen mesh, effectively improve screening effect Rate.
